Application filed February 9, 1924. Serial-No. 691,636.

To all whom t may concern:

Be it known that I, HENRY M.- SHEER, la

' citizen of the United States, residing at Quincy, in the county of Adams and State of Illinois, have invented certain new and vuseful Improvementsin Burners, of wh1ch the following is a specification.

My invention relates to an improvement in burners.

This invention therefore consists 1n .a burner bowl having a very shallow oil groove therearound, and provided w1th. a deep oil well into which the supply pipe discharges. This deep oil well with its restricted area will permit a widey range of flame adjustment and permanent flame control. In burners of this type, when the depth of oil is increased, even the smallest fraction of an inch, the flame will suddenly flare up and burn high, probably smoke, and, if the oil level is reduced, the flame will as suddenly drop low and 1s likely to go out.

The width of the deep oil well, or the surface area at the top must be s ubstantially in direct proportion to the d1ameter of the burner bowl, and, due to the sloping vsides of the well, the area will be in direct proportion to the depth of oil in the oil well, so that the flame will th en be 1n direct relation to thedepth of o1l 1n the deep oil well, it being unnecessary for the oil to reach or enter the shallow grooveof the burner bowl, in fact they object of the present invention is to prevent the oil from reaching or flowing into the shallow groovel and flooding the burner.

A deep restricted oil well will producel a gradual change in the flame, since the oil must be vraised or lowered considerably to produce a noticeable effect on the flame.

The present burner bowl is of the true wick-A less type, using no asbestos wick or lighting ring, and no vaporizer of any kind since the amount of vaporization of oil in the deep well will be sufficient to operate the whole burner and this vapor spreads out as it rises and becomes superheatedand converted into gas.

In the accompanying drawings Fig. l is an elevation with parts in section;

F1g. 2 1s a fragmentary plan View;

Fig. 3 is a'vertical section on line 3-3 of Fig. 2;

Fig. 4 is a view in character similar to Fig. l showing a slight modification;

Fig. 5 is a fragmentary plan view of th same; Y p

- Fig. 6 is a section on line 6 6 of Fig.

Fig. 7 shows a slightly modified form of nipple; and

Fig. 8 is a diagrammatic view of the burner and means for supplying oil thereto.

The numeral 1 represents the shallow groove of the burner bowl A, and 2 is the deep oil well. -In the construction shown in Figs. 4, 5 and 6, there is a nipple 3 at the center of the well, and this has a hole 4 at the top, and two holes 5 at the bottom which communicate with a chamber 7 within the nipple and the deep oil well. The oil lever is regulated by any well-known oil level device, so that the oil is always maintained below the top ofthe chamber. This construction permits' carrying the true or actual oil level well within the burner well and any suitable means I8 is provided for this purpose. The oil passes from this nipple to the burner 'well through two small openings 5 located on a line with the bottom of the oili well. Instead of the two small holes, a very fine slot 6 could be used as shown in Fig. -7. Carrying the oil level within the burner well is a means of solving the problem of practical and perfect oil level flame control, which has heretofore been repeatedly attempted, but never fully accomplished.

The delivery of oil from the chamber to the oil well through the small holes 5, or the slot 6, is not affected, and cannot be affected in any way by the action of the flame. The flame can be much more closely adjusted with this construction than where the whole groove is used.

To start the burner, the shallow oil groove, together with the deep well, must be filled with gasoline, alcohol, or the like. By the time this priming fue] is consumed, the burner will be heated, and the oil feed'can then be turned on to fill the oil well to the desired height so that the amount of vaporization of oil in the deep well will be suflicomes superheated. Thus after the priming has been effected, itis not desirable to have any oil in the shallow groove, all the burning surface of the oil being within `the oil well.

Itis understood that I am not dependentupon the nipple to prevent suctionA on the oil supply. s'a matter of fact., the deep well or chamber v2 of Figs. l, 2 and 3, prevents suction to a large extent since the oil inlet is below the lowest part of the level of vaporization. In other words, some oil will, always remain in the bottom of the 4well of, said well having substantially flat, slop-k ing ends, and having an inlet adjacent the bottom thereof for receiving oil, and means for normally maintaining the oil level at a point between the top and bottom of the o il wellproviding a burning surface within the oil well, the vapor rising from the burning surface and passing substantially around the groove. l

2. A burner including a shallow groove, an oil well, and a nipple projecting upwardly from the bottom of thel well` said nipple l having an orifice at the top and bottom.

3. A burner including an annular shallow groove and a deep oil well extending' downwardly from a point in the bottom of the groove', and a nipple extendingupwardly from the bottom of the well to a' point above thel bottom of the groove.

Ll. A burner including an annular shallow-groove and a deep oil well extending downwardly from a point in the bottom of the groove, and a nipple extending upwardly from the bottom of the well to a point above' the bottom of the groove, said nipple hav-ing an outlet at points above and below the level of the bottom of the shallow groove.

In testimony whereof I affix my signature.

HENRY M. SHEER.
